ABSTRACT

For the high speed section of IPMSM sensorless operation, this paper mainly studies the Model Reference Adaptive System (MRAS) speed estimation algorithm. Firstly, the basic principle of model reference adaptive algorithm is expressed. Then the reference model and adjustable model of MRAS are constructed, and the adaptive law of speed estimation based on Popov's super stability theorem is designed. Finally, the sensorless control of IPMSM based on MRAS is carried out. The MATLAB modeling simulation of the system verifies the effectiveness of the designed speed estimation algorithm.
